IMPROVEMENT IN CATTLE-PUMPS.

Specification forming part of Letters Patent No. 52,01 l, dated January16, 1866.

To all whom it may concern:

Be it known that I, J. B. ATWATER, of Olii. cago, in the county of Cookand State of lllinois, have invented a new and Improved Oattle-Pump; andl do hereby declare that the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawings,making a part of this specification, in which- Figure lis a top view ofthe improved pumping apparatus arranged within an iuclosure. Fig. 2 isan elevation of the hinged platforms attached to the pumping-lever, aportion of the fence being removed. Fig. 3 is a vertical longitudinalsection of the loaded pumping-lever for operating the pumping apparatus.Fig. 4 is a vertical sectional view through the hinged platforms in adepressed state. Fig. 5 is an enlarged sectional view of one oftheplatforms, showing the mode of pivotingitto thelong arm of thepumping-lever.

Similar letters of reference indicate corresponding parts in the severalfigures.

This invention relates to that class of stockpumps which are constructedin such manner that the animals effect the raising of water themselveson approaching the trough from which they drink.

Pumps which have hitherto been constructed to operate upon this planfail to elevate a sufficient quantity of water to quench the thirst ofthe animals on account of a want of power, which cannot be practicallyderived from the weight of the animals alone.

Another objection to pumps of this class which have hitherto been usedis that only one animal can drink at a time, and no provision is madefor supplying water to herds which may be in adjoining fields.

The main object of my invention is to arrange a contrivance forelevating water, and also a drinking-trough, within a yard or inclosureof a suitable description in such manner that the animals, upon enteringor leaving such inclosure, will operate the pump and supply the troughwith water, as will be hereinafter described.

Another object of my invention is to combine a platform over which theanimals are required to pass to obtain water with a heavilyloaded leverin such manner that the xed weight upon the lever is caused to elevatethe water from the well, instead of the weight of the animal or animals,thus admitting of the employment of any required amount of power and theraising of a larger amount of water from a well of a given depth thancould be effected by the weight of the animals alone, as will behereinafter described.

To enable others skilled in the art Vto understand myinvention, I willdescribe its construction and operation.

In the accompanying drawings, Arepresents a long lever, which consistsof two beams of an equal length, that are secured to the sides oftrussed braces, as shown in Figs. l and 3, for the purpose of obtaininggreat strength and steadiness. This lever is mounted upon two verticalstandards, a a, which' constitute its fulcrum, and upon one end-theshort arm of the lever-a box, B, is secured for receiving a weight. Thisbox is merely intended to keep in place a number of heavy weights. Itmay be dispensed with and the weight or weights secured in any otherconvenient manner, so that they will not be liable to fall off thelever. Attached to this loaded short arm of the leverA is the piston-rodb, for working any suitable pump, which is constructed to elevate waterfrom a well, e, by the descent of the loaded arm of the lever A.

.At or near the end of the long arm of lever A, and on the longitudinalsides thereof, two beams, d d, are pivoted by coupling-pins e e, and tothese beams platforms G O are connected by means of pivoted side straps,f j'. These two platforms O O have rails D D on one side, for preventinganimals from stepping oli' these sides. The rear or outer ends of theplatforms are mounted upon small rollers or wheels g g, which allowthese ends to move freely when the long arm of the leverA is depressed,so as to bring the platforms down to the nearly-hori zoutal plane, asshown in Fig. 4.

On one side of the lever A is a trough, Gr, which may be of suijicientcapacity to allow a number of animals to drink at the same time. Thistrough is supplied with water from the pump at every downward stroke ofthe short or loaded arm ofthe lever A.

The apparatus which I have above described is inclosed by means ofafence, J, so that the animals will have to enter at the opening Jf, passover the platforms C O, and leave these platforms before they can reachthe trough Gr,v in doing which the animals depress the long arm of thelever A and allow the weight on the short arm to act directly upon thepump-piston. Then, upon leaving the yard or inclosure, the animals willagain operate the pump in the same manner.

The fulcrum of the lever Ais located nearer one end of this lever forthe purpose of causing the weight of a small animal passing over theplatforms O C to lift the load on the short arm of this lever, whichload may, in some instances, have to he heavier than several of theheaviest animals in order to elevate the required quantity of water.Hence it is that provision is made for allowing one or more animals toelevate the weight on the lever, which weight will descend as soon asthe platform are relieved of their load. f

By arranging the pumping apparatus within the yard or inclosure, asshown in Fig. 1, and making this yard sufiiiciently large, any numher ofanimals can drink at the same time, and while this is the case, it willbe seen that there will always be a sufficient quantity of Water pumpedup from the well for those that pass into the inclosure. When theanimals leave the inelosure after drinking they again operate 1.Arranging a stock-pumping apparatus,

and also a drinking-trough, within a yard or inclosure in such mannerthat the animals, upon entering or leaving such inclosure, will operatethe pump and supply the trough with water, substantially as described.

2'. The pumping-lever A, having platforms (l C applied to one arm and aweight kapplied directly to the other arm, substantially as described.
